We're reading a lot lately about how the producers of Borat set up ordinary citizens in order to mock them in the film and here we see how Sacha Baron-Cohen likes having the tables turned on him as his "cousin" Horat crashes the L.A. premiere and ambush interviews him. Sacha Baron-Cohen enters the clip at the 5 minute 30 second mark and I'd swear that the reaction we see is Baron-Cohen breaking from character.
